PERPETUAL CALENDAR.

Specification of Letters Patent.

Patented. n ov. 26, 19.1.8.

Application filed June 5. 1917. Serial No. 173,045.

To all whom it may concern Be it known that FRANK 1t. Mourns, a citizen of the United States, residing at Berkeley, in the county of Alameda and State of California, has invented certain new and useful Improvements in Perpetual Calendars, of which the following is a specification.

This invention relates to calendars and has as its principal object the construction of such a device involving certain sliding scales which carry numbers that designate years and dates of the month and which, when properly set, relative to certain fixed designations of the months, calendar for the desired month.

One of the principal objects of my present invention is to arrange the various numeral carrying slides in such a manner that the days of the week are arranged in. their customary order that is, with Sunday on the left and Saturday to the right.

A still further object of my invention is to so adapt the device that it may be used as a tip for a pencil or other writing instrument.

With these and other objects in view, the invention consists of certain novel features of construction, combinations and arrangements of parts hereinafter described and more specifically pointed out in the appended claims; it being understood that changes in form, proportion, size and minor details of construction within the scope of the claims ma .be resorted to without departing from't 1e spirit of the invention or sacrificing any of the advantages thereof.

Referring to the drawing forming a part of this specification,

Figure 1- is a view in a calendar embodying my tio'n.

Fig. 2- is a same.

front elevation of improved invenv ew in rear elevation of the Fig. 3- is a transverse view in cross section.

Fig. 4- is a view in front elevation of a modified form of a calendar having a more limited capacity than the one shown in Fig. 1. v

Fig. 5 is a view in elevation of the calendar as applied to a cylindrical surface.

Fig. 6- 1s a view in section o'f the form Fig. 7' is a view in front elevation of will give the correct Fig. 8 is a developed view of the tables oi figures used in connection with the form shown in Fig. 7.

Referring to correspoinling parts of the several views by the same name 'als of refer cure and more particularly to Figs. 1, 2 and 3, 1 denotes a flat container or iramc formed of any suitable material such paper-board, wood 0 metal. This frame is provided with upper and lower guide-ways 2 and 3 in, which is slidably mounted the flat rectangular member 4.

The frame 1 is provided on the front with. upper and lower openings 5 and 6 respectively, through which the surface of plate 4.- may be viewed. The member L is in turn provided with guideways '7 and 8 in which is slid-ably mounted a card 9, the suface of which may be viewed through an opening 10 in card 9, which opening directly under opening 5.

On the surface of container 1 adjacent the upper edge or opening 5 are provided the designations l1 for the days of the week beginning with Sunday and ending with Saturday, thus forming the heads for seven parallel columns. On the bridge piece 12 between the openings 5 and 6 are a like number of divisions in which are printed the months of the year as designated at 13.

That portion of the member 4 which is exposed to view through opening 6 is provided on its face with numbers 15, commencing at O0 and terminating with 9), these nun \bcrs representing the two terminal digits of the years. Certain of these numbers which are the terminals of leap year, are provided with distinguishing marks as shown at 14 which indicate that those numbers are to he used for the months of January and February of the leap years. For the other months of leap years the corre sponding undesignated numbers are used.

On the face of member 4, above the bridge piece 12 but below the lower edge or" opening 10, are provided numbers indicated by 15 which correspond to the initial two digits of the years. Both the numerals 15 and 15' are arranged between parallel lines Card 9 has six rows of figures arranged in eighteen vertical columns spaced the same as the days aboveopening 5. The figures designated by 16 run from 1 to 31 and are so 3o 17 are under the month, June.

[dual arranged that when viewed through the opening 5 a complete set of figures from to 31 is visible. In other words any seven adjoining columns will show consecutive 3S numbering from 1 to 31. Card 9 is provided ivith pointers or indicators 19 and 20 which are used in setting the calendar.

, A container 1 on the back is provided with narrow slots 21.5and 22, the member 4:

it: having a suitable tab or button which extends through slot 21, whereby this mem .ber maydoe shifted from side to side. Likewise card 9iis provided with a slot 23 which -.is in alinement with slot 22 and is provided I with a tab 25 extending through these two slots whereby the card 9 may be shifted in its guideways. To set this form of calendar for any month withinits capacity, the card 9 is 420 moved until either the indicator 19 or points to the number 15 which designates the initial digits of the year and then the card 4 is moved until the terminal digits of the desired year are under the month for which the calendar is to be set.

Thus, as shown in Fig. 1, the calendar is -set for June 1917, since as previously described, the pointer 19 is opposite the digits 19 and in the lower opening, terminal digits It will be" noted that the numerals designating the dates of the month, appear within the opening '10 in their customary relative order. If the calendar isto be set for January or February of a leap year, then the specially designated numeral 14 for that year is brought under the desired month.

in the form shown in Fig. 4:, the frame 30 is provided with a sliding card 31 and has openings 32 and 33. Above opening 32 are printed the days of the week denoted by 34c and above opening 33, the month of the year, as shown :in 35. 1

On the lower part of slide 31 are the numorals 86 denoting the years and on the upper part of this slide are numerals 37 denoting the days of the week. In this form, a slot 37' is provided through which extends a tab or other. means 38 by which so the slide 31'may be moved. To set this form of my oalendar, it is only necessary to move the slide 31 until the year is under the corresponding month when the numerals 37 will appear in the opening 32 in their proper relative position for that month. in the cylindrical form shown in Fig. 5, a member 40 is provided having suitable means for retaining a revoluble band 4:1. The latter is provided with openings 4-2 and to. 43 through which may be viewed the figures at and 45, the former denoting the days of the week, the latter the terminal numerals at the years of any given century or portion thereof. This form of calendar is merely the form shown in Fig. l wrapped into a resents cylinder and a stop 4:? is provided for limiting the rotation of member i1. This device is set by turning the member 41 until the designation of the month, as denoted by 46, is above the column containing the terminal numeral of the given century.

This latter form of my invention may be made very small and compact so that the same may fit over the end of a pencil furnishing a calendar which is readily acceptable and which it is not necessary to change separate slips of paper in order to keep it up to date. This form may also be provided with a suitable extension 49 which forms a retaining clip for the writing instrument. Instead of making the numerals of limited. extent and providing the stop d7, they may be printed as shown in Fig. 8, the length of the rows being just suliicient to encircle the supporting surface. a

I claim as new and wish to cover by Letters Patent:

1. A calendar comprising a member having rectangular openings, a card movably mounted with respect to said openings, designations carried by said member adjacent an edge of one of said openings representing the days of the weeks and adjacent a parallel edge of one of said openings representing the months, a set of figures indi cating the days of the month carried by said card and a set of figures denoting years carried by said. card, said figures being adapted to be viewed through the said openings.
